Relink new next section AFTER SectionNameToChange in run-time You can link section order the way you like in editor, but in run-time if you'd like to change it dynamically, use this function to relink the next section For example, you can have Start->Loop->Loop->Loop.... but when you want it to end, you can relink next section of Loop to be End to finish the montage, in which case, it stops looping by Loop->End.
